In order to look into this, I need to understand what your goal is first. I see ShadeDBZ set as your submitter name on your profile (this field is shared between all four sites) which should be auto-suggested for your new submissions. If that's what you're going for, there shouldn't be anything else to do. If, however, you're trying to update your name on your existing submissions on tMR and tTR using that form, you're actually seeing the result that you should be. That field only affects what is auto-populated for new submissions - renaming and merging of submitters is limited to admins so people can't arbitrarily "steal" someone else's sheet. If this is what you're trying to accomplish, let me know your old name and the new name you're trying to change it to (I assume ShadeDBZ?) and I'll merge them for you.
